Blood Emperor Jircniv, ruler of Baharuth Empire, refused to apologize after sending the Workers to the Group of Nazarik, so, Ainz Ooal Gown decided it is time to vanquish humans from the land. But he can’t do it alone.
Ainz learns about a secret civilization that went into hiding to protect themselves from humans. Maybe they would join him in his crusade.

But their rulers, Princesses Celestia and Luna would accept the alliance, or Lord Ainz would have to ‘persuade’ them first?

Princess Celestia: Goddess of the Sun, ruler of Equestria, beloved Princess of ponies. She is loved by all, and loves all in return. A calm and wise ruler, she sits on the throne in Canterlot, maintaining peace and harmony throughout the land.

What most don't know is that her past is much darker: She was once a commander of legions, a warrior and scientist of unmatched skill. Thousands of monsters and abominations fell to her forces, slain in the name of an old leader, one entombed within his own throne. Free of her old form, free of the powers of Chaos, she was cast into a new realm, in a new form, with a new lease on life.

She is the God Emperor, Eternal Ruler of Equestria and Lord of the Imperium of Man.

Comments contain spoilers. YOU HAVE BEEN WARNED!!!

This story is a sequel to Princess Celestia The Changeling Queen: Stories Behind the Mask

At the Royal Wedding, Chrysalis and the Changelings were revealed to all of Equestria.

But another mask was torn away that day. A mask born for a thousand years. A mask created on one promise. A mask, that has become synonymous, fused, to its bearer.

A mask that when ripped off, causes Twilight, her friends and Luna to question everything they ever knew about the one pony, one very important pony.

At the Royal Wedding, the meaning of the phrase 'Princess Celestia' changes forever.

NOTE: Chrysalis is NOT Celestia!!! That'd be impossible to pull off.

Princes Cadence is about to get the Best mothers day gift she would ever ask for

In this one-shot idea, Fluttershy asks her friend Discord if he would be interested in taking up the job as a teacher at the new School of Friendship. Discord agrees to teach them something if he were given a chance to test-drive it by having a few students to see if he would take up the job. What follows is a lesson on the meditations of Reniegh Haycartes.

"So I walk up on high,/And I step to the edge,/To see my world below./And I laugh at myself,/While the tears roll down,/'Cause it's the world I know./Oh it's the world I know." -Collective Soul, ‘The World I Know’

Applebloom turns seventeen years old. Eager to become a grown pony, her strong desire to help out around the farm takes hold. However, she is quick to realize that she might not be as ready to grow up as she thought when she begins to have odd feelings for a small purple dragon. Will she be able to fully blossom into the mare she wants to become?

A delinquent young alicorn named Luna just transferred to the Royal Crystal Academy, and Drying Paint has fallen head-over-hooves in love. But she doesn't care about him — or seemingly anything, except for the dark, mysterious gathering place she disappears to on weekends.

Paint might just find a chance to win her heart there. But the shadows hold dangers he never would have expected, and everyone must walk into the darkness alone.

Highly Recommended by Present Perfect! "It's won one contest and taken second in another … because it's outlandish, ballsy, and utterly unique. Read it."

Winner of Cynewulf's Worldbuilding Contest! "Horizon manages to hit both the kind of reader who likes Infinite Jest and the kind who hasn't cracked a physical book since high school, and he does so simultaneously. This is one of his better stories."

Won second place in the 9/2017 "True Colors" Writeoff (as a first draft)! Then third place in the Lunbra group's "An Unexpected Meeting" contest! Also featured by Seattle's Angels!

Rated ★★★★ by Louder Yay! "Both really good and really interestingly different, and that's a combination I can get right behind. An easy recommendation."

Praise for the Writeoff version:
"Seriously though, Loveless is one of the coolest things I've yet seen in the fandom." —CoffeeMinion
"Dear god I love this so much. ... The story crashed into me with energy, style, and pizzazz." —MrExtra
"Literally the story of how gothic clubbing destroyed the Crystal Empire." —horizon

"I'm not the best at putting my feelings into words... Meet me on the roof after school. I need to tell you something. If I don't, I'll regret it for the rest of my life."

"Please don't leave me waiting..."

Who would have thought a pony and a changeling could have children together. I certainly wouldn't have. This is Shining Armor, and I'm in a weird situation. Chrysalis has shown up to my home and dropped a kid off stating that it was our son.

What will Cadance think? How am I going to raise a changeling child? Why does Chrysalis keep coming into my life, and why am I finding it harder to keep her away? Hopefully answers can be found with as little problems as possible. Oh who the Tartarus am I kidding, my seed is a changeling! There's bound to be a problem along the way.

Story inspired by Bakki's excellent fanart.
